*) SECURITY: Fix a bug in the calculation of the buffer size for the line
continuation facility in Apache's configuration files which could
lead to a buffer overflow situation.
*) Make documentation and error messages of APACI's --activate-module=FILE
*) Fix the gcc version check (for enabling the `inline' facility) to
really support all future gcc versions >= 2.7 until we know more.

*) Let APACI's configure script correctly complain for unknown --enable-XXX
and --disable-XXX options. [Ralf S. Engelschall] PR#3958
*) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
against libap.a and use its ap_snprintf() instead of sprintf() to avoid
possible buffer overflows. [Ralf S. Engelschall]
*) Remove no longer used non-API function ap_single_module_init().
[Ralf S. Engelschall]
*) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
[Wilfredo Sanchez]
*) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
to make platform installations easier. [Wilfredo Sanchez]
*) In configure, do not append the target name to the directory path if
the path already contains "apache". [Ralf S. Engelschall]
*) SIGPIPE is now ignored by the server core. The request write routines
(ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
correctly check for output errors and mark the connection as aborted.
Replaced many direct (unchecked) calls to ap_b* routines with the
analogous ap_r* calls. [Roy Fielding]
*) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
DBM format mapfiles now uses a 4-way hash table with LRU functionality.
Furthermore map lookups for non-existent keys are now cached as well.
Additionally "txt" maps are now parsed with simple string functions
instead of using ap_pregcomp(). As a side effect a bug that prevented
the usage of keys containing the "," character was fixed.
The changes drastically improve the performance when large rewrite maps
are in use.
[Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
*) Added ap_sub_req_method_uri() for doing a subrequest with a method
other than GET, and const'd the definition of method in request_rec.
[Greg Stein]
*) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
*) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
when the OS allows a DOS drive letter within pathnames. [Brian Havard]
*) Add %V to mod_log_config, this logs the hostname according to the
UseCanonicalName setting (this is the pre-1.3.4 behaviour of
*) Add support for \n and \t to mod_log_config, can be used to produce
more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
*) Added informative error messages for failed munmap() and fseek() calls
in http_core.c. [John Bley, Roy Fielding]
*) Added some informative error messages for some failed malloc()
*) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
is removed. This allows <Directory proxy:*> directives to work and
prevents invalid requests from killing the process.
*) Reorganised FAQ document.
*) src/support/: The ApacheBench benchmark program was overhauled by
David N. Welton: you can now have it generate an HTML TABLE, presumably
for integration into other HTML sources. David updated the ab man page
as well and added some missing descriptions. Thanks!

*) Win32: The filename validity checker now allows filenames containing
characters in the range 0x80 to 0xff (for example accented characters).
[Paul Sutton] PR#3890
*) Added conditional logging based upon environment variables to
mod_log_config. mod_log_referer and mod_log_agent
are now deprecated. [Ken Coar]
*) Allow apache acting as a proxy server to relay the real
reason of a failure to a client rather than the "internal
server error" it does currently. The general exposure mechanism
can be triggered by any module by setting the "verbose-error-to"
note to "*"; this allows more than just proxy errors to be exposed.
[Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086

*) Added a <LimitExcept method ...> sectioning directive that allows
the user to assign authentication control to any HTTP method that
is *not* given in the argument list; i.e., the logical negation
of the <Limit> directive. This is particularly useful for controlling
access on methods unknown to the Apache core, but perhaps known by
some module or CGI script. [Roy Fielding, Tony Finch]
*) Prevent apachectl from complaining if the PIDFILE exists but
does not contain a process id, as might occur if the server is
being rapidly restarted. [Wilfredo Sanchez]
*) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
*) Entity tag comparisons for If-Match and If-None-Match were not being
performed correctly -- weak tags might cause false positives. Also,
strong comparison wasn't properly enforced in all cases.
[Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
*) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
[Brian Havard]
*) Work around a bug in Lynx regarding its sending "Negotiate: trans"
even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
*) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
to util.c for parsing an HTTP header field value to extract the next
list item, taking into account the possible presence of nested comments,
quoted-pairs, and quoted-strings. ap_get_list_item() also removes
insignificant whitespace and lowercases non-quoted tokens.
[Roy Fielding] PR#2065
*) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
code different from 500. This allows the proxy to, e.g., return
"403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455

negotiation algorithm is being used with multiple language variants
and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688

*) Do not round the TCN quality calculation to 5 decimal places,
unlike RFC 2296, because the calculation might need 12 decimal places
to get the right result. [Roy Fielding]
*) Remove unused code to disable transparent negotiation when
negotiating on encoding only, as we now handle encoding too
(though this is nonstandard for TCN), remove charset=ISO-8859-1
fiddle from the fiddle-averse RVSA comparison, and fix bugs in
some debugging statements within mod_negotiation. [Koen Holtman]
*) Fixed a rare memory corruption possibility in mod_dir if the index
file is negotiable and no acceptable variant can be found.
[Dean Gaudet, Roy Fielding, Martin Kraemer]
*) Win32: Add new config directive, ScriptInterpreterSource, to enable
searching the Win32 registry for script interpreters.
[Bill Stoddard]
*) Win32: The compiled-in default filename for the error log is now
error.log, which matches the default in the distributed httpd.conf.
[Paul Sutton]
*) Win32: Any error messages from -i or -u command line options are now
displayed on the console output rather than sent to the error log.
Also the "Running Apache..." message is not output unless Apache is
going to serve requests. [Paul Sutton]
*) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
and use a private significator ('$apr1$') to mark passwords as
being smashed with our own algorithm. Also abstract the password
checking into a new ap_validate_password() routine. [Ken Coar]
*) Win32: The filename validity checker now allows "COM" but refuses
access to "COM1" through "COM4". This allows filenames such
as "com.name" to be served. [Paul Sutton] PR#3769.
*) BS2000: Adapt to the new ufork() system call interface which will
make subtasking easier on the OSD/POSIX mainframe environment.
[Martin Kraemer]
*) Add a compatibility define for escape_uri() -> ap_escape_uri() to
*) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
use `.db' instead of `.pag' not only for FreeBSD, but also when
the NDBM library looks like Berkeley-DB based.
[Ralf S. Engelschall] PR#3773
*) Add ability to handle DES or MD5 authentication passwords.
*) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
*) SECURITY: Avoid some buffer overflow problems when escaping
quoted strings. (This overflow was on the heap and we believe
*) Let src/Configure be aware of CFLAGS options starting with plus
signs as it's the case for the HP/UX compiler.

*) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
and check to see if the tar we wind up with supports '-h'.
[Jim Jagielski] PR#3671
*) A consistent and conservative style for all shell scripts has been
implemented. Basically, all shell string tests use the traditional
hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
to protect against bare null variable strings (ie: wrapping both
sides with double quotes and prepending 'x'). 'x' was chosen
because it's more universal and hopefully easier for old shell
prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
[Jim Jagielski]
*) The status module now prints out both the main server generation as
well as the generation of each process. Also, the vhost info is
printed with '?notable'. [Jim Jagielski]
*) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
and this makes its functions available to things in src/support.
[Ken Coar]
Changes with Apache 1.3.4
*) Renamed macros status_drops_connection to ap_status_drops_connection
and vestigial scan_script_header to ap_scan_script_header_err,
mostly for aesthetic reasons. [Roy Fielding]
*) The query switch "httpd -S" didn't exit after showing the
vhost settings. That was inconsistent with the other query functions.
[Martin Kraemer]
*) Moved the MODULE_MAGIC_COOKIE from before the versions and
filename to the end of the STANDARD_MODULE_STUFF. Its
presence at the beginning prevented reporting of the filename
for modules compiled before 1 January 1999. [Ken Coar]
*) SECURITY: ap_os_is_filename_valid() has been added to Win32
to detect and prevent access to special DOS device file names.
[Paul Sutton, Ken Parzygnat]
*) WIN32: Created new makefiles Makefile_win32.txt (normal build)
and Makefile_win32_debug.txt (debug build) that work on Win95.
Run each of the following from the src directory:
nmake /f Makefile_win32.txt # compiles normal build
nmake /f Makefile_win32.txt install # compiles and installs
nmake /f Makefile_win32.txt clean # removes compiled junk
nmake /f Makefile_win32_debug.txt # compiles debug build
nmake /f Makefile_win32_debug.txt install
nmake /f Makefile_win32_debug.txt clean
[Roy Fielding]
*) Added binbuild.sh and findprg.sh helpers to make it easier for us
to build binary distributions. [Lars Eilebrecht]
*) IndexOptions SuppressColumnSorting only turned off making
the column headers anchors; you could still change the display
order by manually adding a '?N=A' or similar query string to the
URL. Now SuppressColumnSorting locks in the sort order so
it can't be overridden this way. [Ken Coar]
*) Added IndexOrderDefault directive to supply a default sort order
for FancyIndexed directory listings. [Ken Coar] PR#1699
*) Change the ap_assert macro to a variant that works on all platforms.
*) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
search for an underscore on dlsym() (as it's already the case
*) Small fix for mod_env.html: The module was documented as to be _not_
compiled into Apache per default, although it _IS_ compiled into
*) Instead of fixing a bug in the generation procedure for config.status (a
backslash was missing) we remove the bug together with it's complete
context because the special cases of the past can now no longer occur
because of the recent magic for the --with-layout default.
[Ralf S. Engelschall] PR#3590
*) Make top-level Makefile aware of a parallel build procedures (make -j) by
making sure the src/support/ tools are _forced_ to be build last (they
depend on other libraries).

*) Fix installation procedure: Now that os-inline.c is actually used (a
recently fixed bug prevented this) we need to also install os-include.c
in addition to os.h into the PREFIX/include/ location or building of
module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
*) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
allow us to distinguish between a garbled DSO (or even a file which isn't
an Apache module DSO at all) and a DSO which doesn't match the current
Apache API. [Ralf S. Engelschall] PR#3152
*) Two minor enhancements to mod_rewrite: First RewriteRule now also
supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
match case insensitive (this especially avoids nasty patterns like
`[tT][eE][sS][tT]'). Second two additional internal map functions
`escape' and `unescape' were added which can be used to escape/unescape
to/from hex-encodings in URLs parts (this is especially useful in
combination with map lookups).
[Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
*) Renamed the macro escape_uri() to ap_escape_uri() which was
forgotten (because it was a macro) in the symbol renaming process.
[Ralf S. Engelschall]
*) Fix some inconsistencies related to the scopes of directives. The only
user visible change is that the directives `UseCanonicalName' and
`ContentDigest' now use the (more correct) `Options' scope instead of
(less correct) `AuthConfig' scope. [Ralf S. Engelschall]
*) Using DSO, the Server token was being mangled. Specifically, the
module's token was being added first before the Apache token. This
has been fixed. [Jim Jagielski]
*) Major overhaul of mod_negotiation.c, part 2.
- properly handle "identity" within Accept-Encoding.
- allow encoded variants in RVSA negotiation and let them appear in
the Alternates field using the non-standard "encoding" tag-list.
- fixed both negotiation algorithms so that an explicitly accepted
encoding is preferred over no encoding if "identity" is not
included within Accept-Encoding.
- added ap_array_pstrcat() to alloc.c for efficient concatenation
of large substring sequences.
- replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
[Roy Fielding]
*) Major overhaul of mod_negotiation.c, part 1.
- cleanups to mod_negotiation comments and code structure
- made compliant with HTTP/1.1 proposed standard (rfc2068) and added
support for everything in the upcoming HTTP/1.1
revision (draft-ietf-http-v11-spec-rev-06.txt).
- language tag matching also handles tags with more than 2
levels like x-y-z
- empty Accept, Accept-Language, Accept-Charset headers are
processed correctly; previously an empty header would make all
values acceptable instead of unacceptable.
- allowed for q values in Accept-Encoding
- added support for transparent content negotiation (rfc2295 and
rfc2296) (though we do not implement all features in these drafts,
e.g. no feature negotiation). Removed old experimental version.
- implemented 'structured entity tags' for better cache correctness
(structured entity tags ensure that caches which can deal with Vary
will (eventually) be updated if the set of variants on the server
is changed)
- this involved adding a vlist_validator element to request_rec
- this involved adding the ap_make_etag() function to the global API
- modified guessing of charsets used by Apache negotiation algorithm
to guess 'no charset' if the variant is not a text/* type
- added code to sort multiviews variants into a canonical order so that
negotiation results are consistent across backup/restores and mirrors
- removed possibility of a type map file resolving to another type map
file as its best variant
[Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
*) RFC2396 allows the syntax http://host:/path (with no port number)
but the proxy disallowed it (ap_proxy_canon_netloc()).
*) When modules update/modify the file name in the configfile_t structure,
syntax errors will report the updated name, not the original one.
*) Correct some filename case assumptions from WIN32 to
CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
*) For %v log ServerName regardless of the UseCanonicalName
setting (similarly for %p). [Dean Gaudet]
*) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
rather late (too late for some invocations of TestCompile).
This improves the make environment available to TestCompile and
the *.module scripts. [Martin Kraemer]
*) The hashbang emulation code in ap_execve.c would interpret
#!/hashbang/scripts correctly, but failed to fall back to a
standard shell for scripts which did NOT start with #!
Now SHELL_PATH is started in these cases. [Martin Kraemer]
*) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
PR#3336
*) Update APXS manual page: some -q option arguments were missing
and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
*) Cleanup the command line options: `-?' was documented to show
the usage list but does it with an error because `?' is not a valid
command. OTOH a lot of users expect `-h' to print such a usage list and
instead are annoyed for ages by our huge unreadable list of directives.
So we now changed the command line options this way:
1. `-L' => `-R'
Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
very similar to the popular linker option.
2. `-h' => `-L'
Intent: while -l gives the small list of modules, -L now gives the
large list of directives implemented by these modules. This is also
consistent with -v (short version info) and -V (large version info).
3. `-?' => `-h'
Intent: it's now the expected option ;-)
The manual page was adjusted accordingly.

*) Removed recently introduced bugs and disfigurements in APACI:
o fixed argument line processing: using $args was broken: It was not
initialized and using args="$args $apc_option" and even args="$args
\"$apc_option\"" fails in the second processing round for any arguments
containing whitespaces. The only correct way is to use the construct
"$@" (but not possible here) or iterate _both_ times over the implicit
argument line (no argument to for-loop) which is what we now use.
o make --with-layout=Apache the default without creating
redundancy (copying the --with-layout block in the argument parsing
loop). We achieve this by using the "$@" construct together with the
`set' command to prepend --with-layout=Apache to the command line in
case --with-layout is not used.
o fixed auto-suffix handling now that config.layout exists.
Paths which are auto-suffixed are marked with a trailing plus sign in
config.layout and every path now can be marked this way (not only the
four paths for which we do it currently). Additionally the suffix is
no longer a static one. Instead it's now `/<target>' where <target> is
the argument of the --target option or per default `httpd'.
o allow also tabs (and only spaces) where we match whitespaces
o various fixes and cleanups related to used shell coding style
o made Jim happy by replacing `Written by' with `Initially written by' ;-)
o trimmed output of --help to fit into 80 columns
[Ralf S. Engelschall]
*) Added two new core API functions, ap_single_module_configure() and
ap_single_module_init(), which are now used by mod_so to configure a module
after loading. [Ralf S. Engelschall]
*) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
of ap_config.h to allow serialized accept for multiport listens.
[Roy Fielding, Curt Sampson] PR#3120
*) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
of ap_config.h that would skip several defines if DEFAULT_GROUP
was overridden. [Roy Fielding]
*) PORT: The I86 version of DGUX has support for strncasecmp and
strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
*) Fix ordering of definitions in ap_config.h so that ap_inline is
defined before it might be used. [Victor Khimenko]
*) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
*) Make generation of src/Configuration.apaci more robust: It failed to
differenciate between modules when one module name was a postfix of
another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
just XXX (think about totally non-standard names like "apache_ssl", too).
[Ralf S. Engelschall] PR#3380
*) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
since 1.3b7) and make whitespace handling more robust (it failed horrible
when whitespaces were present in the arguments of -D options).
[Ralf S. Engelschall] PR#3240
*) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
creates an external package shadow tree in DIR before the local build
shadow tree is generated under DIR. This way one can have the extracted
Apache distribution tree read-only on NFS or CDROM and still build Apache
from these sources. An automatically triggered VPATH-like mechanism is
provided through the TOP variable, too.
*) Fix negotiation so that a Vary response header is correctly
generated when, for a particular dimension, variants only vary
in having or not having a value for that dimension. [Paul Sutton]
*) Fix negotiation so that we prefer an encoded variant over an
unencoded variant if the user-agent explicitly says it can
accept that encoding. Previously we always preferred the unencoded
variant.

*) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
and the usage page was inconsistent with the functionality and manpage.
[Ralf S. Engelschall]
*) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
They can occur multiple times and their arguments (`xxx') are passed AS
IS to the compiler/linker command. [Ralf S. Engelschall]
*) Fixed possible (but harmless in practice) bug in the DBM lookup
procedure of mod_rewrite: very long keys were truncated.
[Ralf S. Engelschall]
*) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
identifier, currently "Apache" and "GNU" are pre-defined in the file
config.layout. Custom layouts are possible by using FILE:ID as the
argument where the layout ID is taken from FILE.
The config.layout file consists of <Layout ID>..</Layout> sections
where inside those sections "path_variable: path_value" pairs can be
specified. These lines are converted to path_variable='path_value'.
*) Add a DefaultLanguage directive so that files missing a language
extension (e.g., .fr, .de) can be labelled as being some other
default language. DefaultLanguage can appear in <Directory> and
<Files> containers as well as .htaccess files. [Paul Sutton]
PR#1180
*) Fix TARGET configuration when configuring and installing using
APACI configure. TARGET now defines the basename of the configuration
file, startup script, manual page, etc. log_error_core() now reports
the server binary name given by argv[0]. TARGET can now also be defined
with --target=TARGET parameter passed to APACI configure.

*) Fallback to native compilers for IRIX-32 platform. It seems that
a gcc 2.8.1 compiled apache is logging client addresses with all

used to set the document root directory (DOC_ROOT) and the suexec
logfile (LOG_EXEC), respectively. Additionally the --layout option
was changed to show more information about the suEXEC setup.

*) Added the last two WebDAV status codes of 424 (Failed Dependency)
and 507 (Insufficient Storage) for use by third-party modules.
[Roy Fielding]
*) Enabled all of the WebDAV method names for use by third-party
modules, Limit, and Script directives. That includes PATCH,
PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
Improved mod_actions.c so that it can use any of the methods
defined in httpd.h. Added ap_method_number_of(method) for

*) WIN32: Log more explicit error messages if spawning an interpreted
script failed, including the command line used to attempt to execute
the interpreter and the Win32 error code returned. [Marc Slemko]
*) Disable sending of error-notes on a 500 (Internal Server Error) response
since it often includes file path info. Enable sending of error-notes
on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
*) http_config.c would respond with 501 (Method Not Implemented) if a
content type handler was specified but could not be found, which
should have been a 500 response. Likewise, mod_proxy.c would responsd
with a 501 if the URI scheme is unrecognized instead of the correct
response of 403 (Forbidden). [Roy Fielding]
*) SECURITY: Eliminate DoS attack when a bad URI path contains what
looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
*) Fix in mod_autoindex: for files where the last modified time stamp was
unavailable, an empty string was printed which was 2 bytes short.
The size and description columns were therefore not aligned correctly.
[Martin Kraemer] (no PR#)
*) Update BS2000 OS code to work with recent versions. Starting with
release A17, the child fork() must be replaced by a _rfork().
(BS2000 only) [Martin Kraemer]
*) Add the actual server_rec structure of the specific Vhost to the
scoreboard file and avoid a string copy (as well as allow some
further future enhancements). [Harrie Hazewinkel
*) Add APACI --permute-module=foo:bar option which can be used to
on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
in the Configuration[.apaci] file. Two special and important variants are
supported for the option argument: first BEGIN:foo which permutes module
mod_foo with the begin of the module list, i.e. it `moves' the module to
the begin of the list (gives it lowest priority). And second foo:END
which permutes mod_foo with the end of the module list, i.e. it `moves'
the module to the end of the list (gives it highest priority).
[Ralf S. Engelschall]
*) Fix problem with 'apache -k shutdown' and startup event
PR#3255
*) The config parser wasn't correctly noticing a missing '>'
on container start lines (e.g., it wouldn't spot
"<Directory /" as a syntax error). [Ryan Bloom <rbbloom us.ibm.com>]
PR#3279
*) Add a 'RemoveHandler' directive which will selectively remove
all handler associations for the specified file extensions.
*) Properly handle & allow "nul" and ".*/null" in AccessConfig and
ResourceConfig directives on Win32. Also add a note to the effect
of 'useless User directive ignored on Win32' to the errorlog if
a User directive is encountered on Win32.
*) Fix multiple whitespace handling in imagemaps for mod_imap which was
broken since Apache 1.3.1 where we took out compressing of multiple
spaces in ap_cfg_getline().
*) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
initialized correctly and the db_open() call used an invalid mode
*) PORT: DSO support for UnixWare 7
*) Merge the contents of the {srm,access}.conf-dist* files into the
httpd.conf-dist* files. The srm and access files now contain
only comments, and httpd.conf has all the combined contents in
a rational order. [Ken Coar]
*) PORT: DSO/ELF support for FreeBSD 3.0.
*) Add a "default-handler" handler that calls the default_hander()
function which is normally called for static content. This allows
you to override a specific handler. [Marc Slemko]
*) Further simplify checking for absolute paths by replacing an
hard-coded syntax check with a call to a routine we already created to
*) Log an error if we encounter a malformed "require" directive
in mod_auth if we know that we know that no other module can
deal with it. [Marc Slemko]
*) Remove ap_private_extern method of hiding conflicting symbols
on the NEXT platform because it is not correct for all versions,
and the versions for which it is correct are unknown.

is encountered in an .htaccess file somewhere down the tree.
[Ken Coar] PR#2409
*) Minor performance improvement to ap_escape_html(). [Roy Fielding]
*) Fixed a segmentation violation in mod_proxy when a response is
non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
Changes with Apache 1.3.3
*) Added a complete implementation of the Expect header field as
specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
response when we already know the final status, which is mighty
useful for PUT responses that result in 302 or 401. [Roy Fielding]
*) Remove extra trailing whitespace from the getline results as part
of the protocol processing, which is extra nice because it works
between continuation lines, is almost no cost in the normal case
of no extra whitespace, and saves memory. [Roy Fielding]
*) Added new HTTP status codes and default response bodies from the
revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
HTTP Extension Framework (510) specifications. Did not add the
WebDAV 424 and 425 codes because they are bogus. We don't use any
of these codes yet, but they are now available to 3rd-party modules.

*) Fix a possible race condition between timed-out requests and the
ap_bhalfduplex select that might result in an infinite loop on
platforms that do not validate the descriptor. [Roy Fielding]

*) Fallback from sysconf-based to plain HZ-based `ticks per second'
calculation in mod_status for all systems which don't have POSIX
sysconf() (like UTS 2.1) and not only for the NEXT platform.
*) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
mod_auth_db by using ap_getword_white() (which uses ap_isspace())
instead of ap_getword(..., ' ') (which parses only according to spaces
Ralf S. Engelschall] PR#3105
*) Fix the SERVER_NAME variable under sub-request situations (where
`UseCanonicalName off' is used) like CGI's called from SSI pages or
RewriteCond variables by adopting r->hostname to sub-requests.
*) Fix stderr redirection under syslog-based error logging situation.
*) Document `ErrorLog syslog:facility' variant of error logging.
*) Fix http://localhost/ hints in top-level INSTALL document.
*) Quote paths in default configuration files. [Wilfredo Sanchez]
*) PORT: Remove extra HAVE_SYS_RESOURCE_H define for RHAPSODY since
it is now taken care of properly by the header file tests.
*) Fix problem with scripts and filehandle inheritance on Win32.
*) Win32 name canonicalisation could end up using the server's
working directory to fill in some blanks. [Ken Parzygnat
*) Correct invalid assumption by ap_sub_req_lookup_file() that all
absolute paths begin with "/" -- because they don't on Win32.
*) Add [REDIRECT_]VARIANTS environment variable to mod_speling
so that ErrorDocument 300 processors can reformat the list
if desired. [Ken Coar] PR#2859
*) Add +/- incremental prefixes to IndexOptions keywords, and
enable merging of multiple IndexOptions directives. [Ken Coar]
*) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
*) Reconstructed the loop through multiple htaccess file names so
that missing files are not confused with unreadable files.
[Roy Fielding]
*) The ap_pfopen and ap_pfdopen routines were failing to protect the
errno on an error, which leads to one error being mistaken for
another when reading non-existent .htaccess files.

handle the creation of modules.c [Jim Jagielski]
Changes with Apache 1.3.2
*) Fix bug in ap_remove_module(), which caused problems for dso's
who were the top_module. [Doug MacEachern]
*) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
mod_auth_db to both be friendly to users who wants to use this version
and to avoid problems under platforms where only version 2.x is present.
*) When using ap_log_rerror(), make the error message available to the
*ERROR_NOTES envariables by default. [Ken Coar]
*) BS2000 platform only: get rid of the nasty BS2000AuthFile.
You now must define a BS2000Account name for the server User.
This has fewer security implications than the old approach.
[Martin Kraemer]
*) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
platform to make the braindead HPUX linker happy. Notice, for the module
DSOs we don't have to use this, because these are loaded manually (and
not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
*) Make PrintPath work generically instead of having one version
strictly for OS/2. [Jim Jagielski, Brian Havard]
*) Fix the recently introduced C header file checking: We now use the C
pre-processor pass only (and no longer the complete compiler pass) to
determine whether a C header file exists or not. Because only this way
we're safe against inter-header dependencies (which caused horrible
portability problems). The only drawback is that we now have a CPP
configuration variable which has to be determined first (we do a similar
approach as GNU Autoconf does here). When all fails the user still has
the possibility to override it manually via APACI or src/Configuration.
As a fallback for the header check itself we can directly check the
existance of the file under /usr/include, too.
[Ralf S. Engelschall] PR#2777

platform, because it's only supported under version 4.0 and higher. But
because our GuessOS is still unaware of Digital UNIX versions and the
-msym is just to optimize the DSO statup time a little bit it's safe and
best when we leave it out now. [Ralf S. Engelschall] PR#2969
*) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
functions: First all three functions no longer fail on strings containing
"%" chars and second ap_log_printf() no longer does a double-formatting
(instead it directly passes through the message to be formatted to the
real internal formatting function). [Ralf S. Engelschall] PR#2941
*) Allow "Include" directives anywhere in the server config
files (but not .htaccess files). [Ken Coar] PR#2727
*) The proxy was refusing to serve CONNECT requests except to
port 443 (https://) and 563 (snews://). The new AllowCONNECT
directive allows the configuration of the ports to which a
CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
*) mod_expires will now act on content that is not sent from a file
on disk. Previously it would never add an Expires: header to
any response that did not come from a file on disk; the only
case where it still doesn't (and can't) add one for that type of
content is if you are using a modification date based setting.
*) Problems encountered during .htaccess parsing or CGI execution
that lead to a "500 Server Error" condition now provide explanatory
text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
[Ken Coar] PR#1291

*) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
a common problem of (mis-administrated?) IIS servers, make the apache
proxy immune to these errors (and ignore the duplicates, but log
the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
*) The <IfModule and <IfDefine block starting directives now only
allow exactly one argument. Previously, the optional negation
character '!' could be separated by whitespace without a syntax
error being reported, albeit defeating the IfModule functionality
(enclosed directives would ALWAYS be executed). By using the
stricter syntax, these hard-to-track errors can be avoided.
[Martin Kraemer]
*) Simplify handling of IndexOptions in mod_autoindex -- and BTW
cause the standalone FancyIndexing directive to logically OR
into any existing IndexOptions settings rather than wiping
them out. [Ken Coar]
*) Changes in ftp proxy: make URL parsing simpler by using the
parsed_uri stuff.
+ Add display of the "current directory" in cases where it's
different from the supplied path (e.g., ftp://user@host/ lives
in /home/user, not in /, therefore clicking on "../" in the
starting directory might send us to /home/).
+ When ftp login fails, (esp. when a user name was part of the
URL already), we now return [401 Unauthorized ] to allow the
browser to pop up an authorization dialog. This makes passwords
slightly less visible (they don't appear in the regular log files)
and implements a functionality that other www proxy servers
already offered.
[Martin Kraemer]
*) Triggered by the recent "Via:" header changes, the proxy module would
dump core for replies with invalid headers (e.g., duplicate
"HTTP/1.0 200 OK" lines). These errors are now logged and the
core dump is avoided. Also, broken replies are not cached.

plop gmon.out profile data for each child [Doug MacEachern]
*) Use the construct ``"$@"'' instead of ``$*'' in the generated
config.status script to be immune against arguments with whitespaces.
*) Replace the inlined information grabbing stuff for the configuration
adjustment feature (no --without-confadjust) with calls to a new helper
script `buildinfo.sh' which is both more flexible and already proofed to
be more robust against platform differences. This mainly fixes the
recently occured ``sed: command garbled: ...'' problems.
